T Design of whole scheme of substation automation system based on IEC61850 ECHNOLOGY Science and technology Wen / Yu Bo - [Abstract] this paper discussed [Key words] substation on the overall design of substation automation system based on IEC61850; automation system; monitoring system; fault tolerance; main transformer protection 1. introduction Digital substation based on IEC61850 (hereinafter referred to as digital substation), signal output and control input intelligent primary equipment using digital technology, substation secondary circuit two in the design of conventional relays and programmable logic circuit by software instead of conventional analog signal, digital signal was replaced by conventional control cable cable instead of two times. Circuit design simple so that the reliability of substation automation system has been further improved. 2. overall system requirements An IEO device layer and inter station background (including the protection device and control device) communication using IEC61850 communication protocol standard; between measurementcontrol spacer layer using GOOSE fast message level communication mechanism based on the interlayer contact between the total locking function; interval layer protection device adopts level communication mechanism based on GOOSE fast message cancel, protection device between the screen cable; in view of the safety and stability of substation equipment
